Tensorflow android cmake build can't find python

Question

I'm trying to build tflite in my android project using cmake. I've managed to work this approach on the linux (debian) version of the same project.When compiling the arm64 version I followed the official docs When I open android studio and press build/run on top right corner, I get this error:

In file included from /home/user/Desktop/official_stuff/tensorflow_src/tensorflow/lite/python/interpreter_wrapper/numpy.cc:17:
In file included from /home/user/Desktop/official_stuff/tensorflow_src/tensorflow/lite/python/interpreter_wrapper/numpy.h:49:
In file included from /usr/include/python3.9/Python.h:8:
/usr/include/python3.9/pyconfig.h:9:12: fatal error: 'aarch64-linux-gnu/python3.9/pyconfig.h' file not found

When I open the file that throws the error I see the this line indicating that it's searching for it in the system:

#include <aarch64-linux-gnu/python3.9/pyconfig.h>

I ran sudo find / -name "aarch64-linux-gnu" to see whether I have that file or not and indeed I have this file installed:

user@debian:~$ sudo find / -name "aarch64-linux-gnu"
...
/home/user/toolchains/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/aarch64-linux-gnu/include/c++/8.3.0/aarch64-linux-gnu

/usr/share/gdb/auto-load/usr/lib/aarch64-linux-gnu
/usr/include/finclude/aarch64-linux-gnu
/usr/include/aarch64-linux-gnu

I located inside /usr/include/aarch64-linux-gnu and indeed saw /python3.9/pyconfig.h.

The way I did everything is this:

1. sudo git clone https://github.com/tensorflow/tensorflow.git /home/user/Desktop/official_stuff/tensorflow_src
2. curl -LO https://storage.googleapis.com/mirror.tensorflow.org/developer.arm.com/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz
3. mkdir -p ${HOME}/toolchains
4. tar xvf gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz -C ${HOME}/toolchains

ARMCC_PREFIX=${HOME}/toolchains/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-
ARMCC_FLAGS="-funsafe-math-optimizations"
cmake -DCMAKE_C_COMPILER=${ARMCC_PREFIX}gcc \
  -DCMAKE_CXX_COMPILER=${ARMCC_PREFIX}g++ \
  -DCMAKE_C_FLAGS="${ARMCC_FLAGS}" \
  -DCMAKE_CXX_FLAGS="${ARMCC_FLAGS}" \
  -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \
  -DCMAKE_SYSTEM_NAME=Linux \
  -DCMAKE_SYSTEM_PROCESSOR=aarch64 \
  ../tensorflow/lite/

6. And then I needed to ran dpkg --add-architecture arm64, apt-get update, sudo apt install libpython3-dev:arm64
7. I simply clicked build ran after connecting my android device. It compiled for a while and then throw the error.

Here is the cmake snippet I ran that contains my tflite inclusion:

set(TENSORFLOW_SOURCE_DIR "" CACHE PATH
  "Directory that contains the TensorFlow project" )
if(NOT TENSORFLOW_SOURCE_DIR)
  get_filename_component(TENSORFLOW_SOURCE_DIR
    "/home/user/Desktop/official_stuff/tensorflow_src" ABSOLUTE)
endif()
add_library(tensorflowlite SHARED IMPORTED)
add_subdirectory(
  "/home/user/Desktop/official_stuff/tensorflow_src/tensorflow/lite"
  "${CMAKE_CURRENT_BINARY_DIR}/tensorflow-lite" EXCLUDE_FROM_ALL
)
...
target_link_libraries(
        my_proj

        tensorflow-lite
)

How can I fix this issue?

Note: I got to this point following a series of questions which all resolved:

1. An undefined error.
2. Question regarding android build.
